Hi, sorry, I will try to make this short. Essentially, what I am trying to do is run a multivariate ARIMA model predicting one variable with another. However, the only R packages I have found to accommodate such an analysis are ARIMAX and VAR. Unfortunately, there don?t seem to be any good tutorials or demonstrations of how to actually perform this analysis in practice, on my two columns of data. I was wondering if anyone knew of a resource that might help (or one that provided an example of r code to accomplish this). Thanks sooo much! [[alternative HTML version deleted]]
